[OpenSIPS-Users] media-relay exception

[nick at uni-petrol.com]

 And I confirm that media-relay run well on openvz host (not virtual 
 environment).
 I found interesting thing when media-relay fail in openvz virtual 
 environment on openvz host in dmesg appear this string:

 Mar 30 20:41:46 kernel: ctnetlink v0.90: registering with nfnetlink.

 Maybe it helps you understand root of the problem.

 Thanks in advance.
